Technical Paper


The work deals with six-level inverter topology for single phase standalone photovoltaic (PV) based micro system with reduced device count. Fundamental switching scheme has been presented using selective harmonic elimination-pulse width modulation (SHE-PWM) method to calculate the switching angles for optimization of harmonics and to eliminate the lowest order harmonic from the system. The Perturb and Observe algorithm is used for tracking the maximum power point for the triggering of DC–DC boost regulator conversion stage. Complete control scheme has been given with different modes of operation. The PV micro system has been simulated and tested in Matlab simulink environment. Total harmonic distortion analysis for the output voltage and current without and with filter has also been carried out for the system under test.
